Research Topics:

Internet routing protocols and their working environments, especially IP multicast routing architecture and the deployment including implementations of IP multicast capable kernel and user code, are my research topics.
Designing effective satellite communication architecture with bi-directional emulation, in order to make it one of the major Internet infrastructures, is also my research target.
My research on wireless ad-hoc networking is about group communication and a practical self-organized secure mechanism.
Standardization of Internet Protocol with participating in several IETF WGs discussions is important to my research part.
